I just deployed my 3.1 BE on the webhotel but it replies with an error, see below.
Do I have the same problem?

The webapp works perfectly locally on my private home network

The highest version that the web host offers is:
"ASP.NET of version 4.0.30319" and that's the one I did select. That's also what I've selected on my private IIS for this app's pool.

I must admit I get a bit confused regarding "app poo"l and ".Net version" and "targetFramework" in the web.config

Regards
Mats

Server Error

Configuration Error

Parser Error Message: The attribute 'debug' has been locked in a higher level configuration.

It seems that you webhosting company doesn't allows debug=true. I'm not sure if that was fixed now, but last time I tried it with debug=false I got problems related to bundled CSS files from different locations.
